He should be one of the most glorified men in America - a leading cardiologist who married his childhood sweetheart and now runs one of the biggest health agencies in the world.

But Robert Califf has rocketed to public enemy number one with parents across the country due to his role in the baby formula crisis.

The 71-year-old doctor was brought back into the fold as FDA commissioner in February and immediately shut down Abbott Laboratories in Michigan.

It has contributed to one of the worst shortages of baby formula the US has ever seen - and it looks set to last for months more.

It is not the first time Califf has courted controversy, with him being slammed for 'turned a blind eye' to the opioid crisis and making millions out of Big Pharma.

He has also found enemies on either side of politics, with both Democrats and Republicans loathing him for ditching public service to cash in in the private sector.

Califf was returned as FDA commissioner by Joe Biden in February having previously held the role between 2015 and 2017 under Barack Obama.

Since then he has become a household name across the country over the agency's failings during the baby formula crisis.

He claimed yesterday Abbott's key site in Michigan would be reopened within the next few weeks but the firm said it had yet to be given the green light.
